This invention relates to manifoldin typewriting machines of the continuous iilhng type, in which a sheet or several plies of work-sheets are fed around"*-a cylindrical I 5 ,platen, said work-sheets having successive corresponding forms printed thereon. A machine of this-type is disclosed in the patent. to Wernery & Smith, No. 1,132,055,

' dated March 16, 1915, in whichthe web com-- prises several plies with interleaved shiftable carbon-sheets. 1 I

The work-sheets may be fed from any suitable source of supply, over the back of a rearwardly-extending table secured to the writer-carriage, thence forwardly through, a

carbon-carrier on said table, where the carf hon-sheets become interleaved between theplies or work-sheets of the web, whence they 4 are .fed forwardly and then downwardly and around the platen to the printing point.

After a form has been-typed, the carbonsheets are shifted rearwardlyrelatively to the work-sheets, to a fresh set offorms succeeding the set of forms previously typed.

, 5 To facilitate .the relative shifting-of the car-.

hon-sheets and the work-sheets, the platen 'is mounted in aswing frame, so that it may be raised toenablethe straightenin out of that portion ofthe web containin g e inter- 0 leaved carbon sheets, so that relative shifting of the carbon-sheets and work-sheets may be readily accomplished. The carbon: carrier is, for this 1311 wardly to a stop and t e work-sheets. are

may be severed by a. suita le knife.- The fresh set of forms may then be typed and 40. may be advanced around theplaten by the usual line-spacing mechanism, during which time the carboi'i-carrier moveslforwardly on gils'table with the carbons and the workeets.

In the past, it has been found that, a rapid line-spacing-operation' which causes .a quick start of the p aten, when said linespacing mechanismrisoperated, either by hand or, by .means of motor-operated car-I 9 ri'age-returning mechanism, there is a slip occasioned between'th'e platen and the-work web, the latter being-held back,'due to the inertia; of the carbon-carrier :which I feeds forwardly with. the web, .duringalinle spacing se, pushed rears.

Said means may-comprise a spring which-is also efl'ective to hold said carbon-carrier inits for-. ward position, and against'thev tension of which the carbon-carrier may moved rear-- 70 wardly for-carbon-dis lacing purposes.

Another object of t e invention is to.pre-

vent the web-from slippinlg rearwardly of the machine after the slack has been created, To th'lsend, there is provided a clam said clamp bein normall efl'ective and 'aving connected ereto a gen-piece which maybe. carried by the carbon-carrier operating handle.

The clamp is also efiective to assist indmwing a freshjsupply of web from'its source dur-' ingv the forward travel of the carbon-carrierL- i A feature-of the invention relates tomeans' to keep the web, as slack is produced, from working down behind the rear paper-table and work-web-presenting table. v v 9 Another-feature of the;1 invert??? relatfisuilz means orpre'ventingo t e we om p' 1 a between the platen and the aperetable w 'lethe slackis being produ Other fe sand advantages willi here inafterappearwfi In, he accompanying t machine showiit the-invention a 151i thereto, the being in 7mmrthef formasuficient created be 4 r weightof the 86 o afreshsetof-Hf with some of the parts omitted, the carbon carrier being still held in its rearmost position and the clam -operating finger-piece having been release by the typist to render the clam eflective, by means of the spring connected to the clamp-controlling fingerpiece, to 'gri the work-web.

Figure 4 1s a view similar to Figure 3, and shows the parts in position after the platen has been thrown back to its normal typing position. the carbon-carrier having been advanced by a spring, to its extreme forward position, to create a slack in the web-behind the platen, and the typed set of forms being severed. I

Figure 5 is a perspective view of the carhon-carrier and its supporting table, showing' the carbon-carrier-controlling spring,

-the carbon-carrier-operating handle and the web-clamp-actuating mechanism,

The invention is shown as applied to an ,Underwood continuous billing machine disclosed in the above-mentioned patent to Wernery & Smith, in which type-bars when 0 eratedby keys, not shown, swing upward y and 'rearwardly to print againstthe front of a cylindrical platen 11 mounted in a swing frame 12 supported on a carriage 13 comprising end bars 14 connected to each A other by a rear bar 15 and a front bar, not

shown. Said carriage is mounted for let-.

ter-feed movements on a rear rail and a front rail, not shown, said rails being supported on the main frame. 17 of the machme.

'The platen is secured to a shaft 18 journaled in end plates 20-of the swing frame.

The machine also comprises a horizontal.

table 21 extending-rearwardly from the machine, and over which a, composite web 22,

" comprising work-sheets 23 and interleaved carbon-sheets 24,is conducted to-the platen. Said table 21 comprises two end bars 25 connected. to each other by a rear bar 26 and a front bar 27, and isconnected. to travel with said carriage by brackets 28 secured to the cross-bar 15 of said carriage and connected to the front bar of said table. Said table is provided near its rear end with rollers 30, carried by brackets 31 secured to said table, to run on a rear rail 32 supported by a. frame 29 secured to the back of the-main frame 17. A carbon-carrier 33, adapted to travel toward and away from the platen, is

provided with rollers 34 to engage rails 35 securedto the end bars 25 to run back and forth on said table. The carbon-carrier comprises a base-plate 36, to the under side of which said rollers 34 are attached, two at each side of the machine. Stepped uprights 37 are mounted on said base-plate, one at each side thereof, on which carbonblades or holders 38 are detachably mounted, said carbon-blades having the rear ends of the carbon-sheets connected thereto.

The work-web 22, which may be fanfolded or comprise separated plies, may be conducted from any source of supply upwardly at the rear of the machine to a turning bar 40 supported on standards 41' at the upper end of said paper-table by side guides 44 supported on a rock-shaft 45- mounted in the carriage-frame.

The \web 22 may be fed around the platen by the usual front and rear feed-rollers 46 and 47 respectively, when the platen is' rotated, which may be done by the usual line; spacing mechanism comprising the linespace wheel 48, or by means of the usual finger-wheel 50; the usual connections, comprising pinions 51 and gears 52, being made between ,the line-space wheel 48 and the platen 11.

.When it is desired to shift the carbonsheets relatively to the work-sheets, "the platen is swung upwardly by means of the swing frame 12 about a rock-shaft 53 which forms part of the swing frame, the swing frame having been previously released by a spring-pressed handle 54 secured to the rock-shaft 45, said rock-shaft having booklike elements 55 to engage pins or rollers 56 on said swing frame to hold the platen in its normal'typing position. After the platen has been lifted, as shown inFigure 2, the carbon-carrier 33 may be pushed rearwa-rdly by a handle 57 to a stop 58- on one of the rails 35 to draw the carbon-sheets rearwardly, said stop being adjustable according to the length of the forms. At the same time 1 the work-sheets 23 may be drawn forward.

to bring their leading edges to a gage 60 'on a gage-bar 61 supported on a front paper-table 62 forming part of the swing frame. typing position, so that the typed forms may be severed by a knife 59 before the commencement of typing of a fresh'set of forms.

The platen is then lowered to'its The carbon-carrier 33, instead of travel- 'ing forwardly with the web during, line sspacing opfration, as in. the Wernery &

mith mac ine, is moved to its extreme forward position after the platen has been lowered to thus produce slack in that portion of I the web between the carbon-carrier and the platen. To so position the carbon-carrier, there is hereinprovided a helical spring 63, one end of which is connected to a bracket 64 secured to the rearbar-26 of the table, the other end of said spring being connected to a pin 65 extendingdownwardly from the base-plate 36 of the carbon-carrier, said spring 63 being conducted over a pulley 66 mounted on a bracket 67 secured to the forll' ward bar 27 ofthe table 21. Withthis arranqement, when the carbon-carrier is pushed rearwardly by means of its handle 57-, the spring is stretched over the pulley 66 and is efiective to return said carboncarrier 33toits forward position as soon as,

the rearward pressure, of the typ'ist, against said handle is relieved, said carbon-carrier bein arrested in its forward'position by a fixe stop 68.- To-ascertain the forward movement of the web 22-with the carbon-carrier, there is provided means to hold said web on the carboncarrier, said means comprising a clamp 70 having a -bar 71 extending between two arms 72, pivoted on studs 73, secured to thestepped uprights 37 of the carbon-carrier,

sai bar 71 engaging-fingers 74 disposedbeneath the web. The. fingers 74 may be of resilient materialto equalize any inequalities and thereby efiectively secure both of the side edges of the webg'tothe carrier. One

of the arms 72 is rovided with an upwardly-entendingar'm 5 having connected thereto at 76 a link 77, the forward end of which is'supported on a stud 78 engagingin aslot 80in said link, the link having a finger-piece 81 located near the "finger-piece 82 of the carbomcarrier-operating handle, by which the link may be drawn'forward to release the clamp 70. To .holdthe clamp-bar 71 against said fingers 74, there is rovided a spring 83 connected between the link and the carbon-carrier-operating hafile, against the tension of which the link maybe drawn for- I wardly, asindicated in Figure 2, to raise the clamp and conse uently release the web priorto a carbon-(lisp acing operation. After the carbon-carrierreaches the position indicated in Figure 2, during a carbon displacing operation, the'fingerpiece 81' may be released, as shown in Figure 3, thus permitting thespring 83 to-render the clamp e'ifective, after which the carbon-carrier 33 may be drawn forwardlvvby-the connected spring 63 to the position shown iii Figure 4, to forma loop 84 in the web to produce the desired slack, the platen having previously been low ered toitstypi'ng position.

- -To revent the web from wor ,fng down 5; behin "the paper-table 43 as the slack is bein produced I by the forward movement of t e carbon-carrier, there is provided a guardlate 85 secured to the frontbar of the tab e. I

To .prevent the web from piling up between the platen 11 and the rear paper-table 43, and also prevent the web from jumping out between the side guides 44,"said side guides are provided with inwardly-extending fingers or pins 86 beneath which the web passes. I

It-will be understood that, after. the sheets have been gaged, they are held against the gage-bar 61 'to keep their leading edges against-the gage 60 while. theplaten 11 is so T being lowered 'to' its typing position, and

the slack in the web after the platenhas been lowered to its typingposition. To this end, the typist may holdv the carbon-carrier against complete forward movement and allow it to-move sufliciently forwardly to allow position, after which the carbon-carrier may e released tobe completely drawn forward by the spring 63 to thus produce the desired slack in'the web. i

It will further be understood the platen to be swung downto its typing the, if 11 web comprising a single ply, or, in other words, a single continuous worksheet, is used, no car consequently it is'not necessary to raise the on-sheets are necessary, and
